Poster for North Carolina Partners in Amphibian and Reptile Conservation

Poster might highlight the MaxEnt model as an example of the outcome of research in the park and emphasize the need for more occurrence data to populate the ATBI database. 
As of Feb. 24, 2014, there are no reptile species modeled already by the All Taxa mapping project.
Some simple facts might help illustrate the need for more reptile data:
  • ​total herp species in park
  • total herp species in the ATBI database
  • total herp species in the ATBI database that have n = 30 or more
  • total herp species in the ATBI database that need more data to be modeled
I think n of 30 or more was settled on by convention in hopes of having a normal distribution (Central limit theorem).
I just looked at this issue for plants – ATBI has ~1,600 vascular plants, but only around 500 have data points that can be modeled.  And of those, 257 have the requisite 30 or more occurrence records.
Total herp species in the Park according to ATBI database:
Class Amphibia – 63 species
Class Reptilia – 41 species
I’m not sure where to get a “species checklist” for total herp species in the park.  Since the ATBI database is “All Taxa,” it seems that yes, all herp species would be included.  However I don’t know that this is true and it would be nice to verify against another source.
It is interesting that the species with the highest number of records is northern copperhead (Agkistrodon contortrix mokasen,) with 233 specimens, followed by the northern black racer (Coluber constrictor constrictor) at 181 specimens.
I took some .tiff images, saved in “Documents/NPS-NICS-Practicum/herpetofauna/ATBI-reptiles-022414” convert to PNG using GIMP (GNU Image Manipulation Program).
